F/A 18 Hornet (PC)

To reach extreme speeds and get where you are going just turn
off crash and all the other stuff that can be damaged in
difficulty, then start a mission and cruise the ground on full
afterburners then when you reach 700mph cut down to 100% and then
your speed will increase to whatever speed you like, but it takes
a very long time to brake to 0.

To reach extreme altitude be a B52G or an AWAC(plenty of fuel)
and contiue straight up on full afterburner till you reach space,
and believe me you will know when you reach space because you
loose control and if you look back well I'll let you see for your
self.
Once when I was in space I saw some mixed up weird lookin lights,
maybe it was a space station or a space shuttle!!!!

These are some commands the manual doesn't give.

Try pressing -shift- G at the same time and someone will tell you
which runway to goto and if it is clear for departure.

Try pressing -shift- 1,2,3,4,5,6,7,8,9,0 at the same time (one
number at a time) and there will be different views of your jet
so you can watch your missiles and bombs fly.

Taxi over to the Reload/Re-Fuel zone and press -apple- X and
shoot yourself in the head with your pistol( all it does is end
whatever mission your on ) and goto debrief. I don't remember but
I think you get court-marshled for executing yourself though.
